It is often found in mixed forests, along streams, and in hilly regions, contributing to the biodiversity of these areas. The tree provides food and shelter for various wildlife species, including birds and insects. Additionally, Symplocos racemosa helps in soil conservation and watershed management, making it an essential component of forest ecosystems.
Conservation Status
Despite its ecological significance and traditional uses, Symplocos racemosa faces threats due to habitat loss, deforestation, and overexploitation. The indiscriminate harvesting of the tree for its bark and other parts has led to a decline in its population in certain regions. Conservation efforts are needed to protect and sustainably manage Symplocos racemosa to ensure its survival for future generations.
Research and Modern Applications

Gastroprotective and antiulcer activity of mixture of Symplocos racemosa bark and Asarum europaeum root.
Abstract : Peptic ulcer is the most common GIT disorder in the present day life of the industrialized and civilized world. The prevention or cure of peptic ulcers is one of the most important challenges confronting medicine nowadays, as it is certainly a major human illness affecting nearly 8 to 10% of the global population and of these 5% suffer from gastric ulcers. The aim of present study is to evaluate the gastric antisecretory and antiulcer activity of mixture of Symplocos racemosa bark and Asarum europaeum root. The mixture of Symplocos racemosa bark and Asarum europaeum root, were dried in shade and powdered coarsely and extraction was done according to standard procedure. The aqueous and ethanolic extract of mixture of Symplocos racemosa bark and Asarum europaeum root was used in the pylorus ligated, aspirin and ethanolic induced ulcer models. The aqueous and ethanolic extract of mixture of Symplocos racemosa bark and Asarum europaeum root showed significant anti-secretory activity as evidenced by decreased pepsin secretion, gastric juice volume and acid output in pylorus ligated rats. Pre-treatment with of mixture of Symplocos racemosa bark and Asarum europaeum root extract provided significant protection against the peptic ulceration caused by aspirin and ethanolic treated rats. It showed significant gastroprotective effects on the stomach wall in aspirin and ethanol treated rats by increasing the gastric wall mucous. The present findings demonstrate that aqueous and ethanolic extract of mixture of Symplocos racemosa bark and Asarum europaeum root has potent antisecretory and antiulcer effects and justify the traditional usage of this herb to treat peptic ulcer.
